Wärtsilä has partnered with cruise operator Carnival’s Holland America Line and Netherlands-based GoodFuels to conduct ship trials using biofuel blends.
Tests were conducted with 100% biofuel to assess the effect on overall engine performance and engine emissions, as well as a 70% diesel / 30% biofuel blend.
The test was conducted on a Wärtsilä ZA40 engine installed on board the Volendam, a Holland America Line vessel.
It is claimed to be the first trial by Wärtsilä on a cruise ship running on 100% biofuel, with previous tests involving lower biofuel blends.
Wärtsilä’s work included the preparation of test protocols and evaluation of fuel and fuel oil test results.
He is also involved in the supervision of tests and post-test analysis such as engine inspections, performance evaluation and measurements of nitrogen oxide (NOx) emissions.
The biofuel trials are expected to help Carnival reduce its carbon per available-day occupancy by 40% by 2030 and expand its alternative fuel strategy in its liquefied natural gas (LNG) program and capacity. battery, fuel cell and biofuels.
It will also enable the firm to achieve its 2030 target for a 50% reduction in absolute particulate emissions to the air and its 2050 target for net carbon neutral operations.
Wärtsilä North America managing director and director of strategic account management Ricardo Opperman said: “We are continuously developing our engine technology to accept and maintain levels of operational and environmental efficiency with various future fuels, including biofuels.
“These 100% biofuel sea trials will be particularly important – for GoodFuels, for Wärtsilä and for the industry as a whole.”
